RTO India — Slot Not Available since last 20 days

Sir,

Refer application number [protected] for learning license slot booking in delhi (Our address falls under janakpuri rto). The required documents have been submitted & payment made online. While going for slot booking on https://sarathi.parivahan.gov.in/; system always getting shows the same error.
We have even tried booking at 1 am as people suggested;but still we donot see any available slot ever. Have been trying for the last 7 days now.
